On the other hand, new JavaScript engine might appear only in newer alpha releases. We will find out very soon.

Opera’s comment:
“There are some reports about an old internal build of 10.5 being available. Don’t run it, the official build on Tuesday is much better and you don’t risk getting nasty trojans on you pc.”

If not the most requested, it is definitely one of the most requested features. I have been requesting it for half a decade or more. I have seen numerous threads pertaining to this in the official forums. It as been requested thousands of times in the past. But, clearly it is something opera is interested in.

And this is one of the reasons I still kee Fx+Lastpass hanging around.

Internal builds normally don’t go through a lot of QA and it is possible that they have a lot of features not enabled. It is also possible that they have some security holes.
Also, since we don’t know the source of the leak, it is quite possible that someone decided to put a trojan alongwith the file and distribute it. So Opera is right in warning users to wait for the official product to be released. It’s a different matter that most people would try to get their hands on it without waiting, but they had to warn them in the first place. I don’t think they did anything wrong.
